Question

Why might the helium balloon float while the other rests on the table?

Answer 2

Step-by-step explanation:

Helium balloons work by the same law of buoyancy. The helium balloon displaces an amount of air (just like the empty bottle displaces an amount of water). As long as the helium plus the balloon is lighter than the air it displaces, the balloon will float in the air. It turns out that helium is a lot lighter than air.
